IsInputKey Method (GcNumberEditingControl)

In This Topic

Determines whether the specified key is a regular input key or a special key that requires preprocessing.

Syntax

Visual Basic
C#

'Declaration
 
Protected Overrides Function IsInputKey( _
   ByVal keyData As Keys _
) As Boolean

'Usage
 
Dim instance As GcNumberEditingControl
Dim keyData As Keys
Dim value As Boolean
 
value = instance.IsInputKey(keyData)

protected override bool IsInputKey( 
   Keys keyData
)

Parameters

keyData: One of the System.Windows.Forms.Keys values.

Return Value

true if the specified key is a regular input key; otherwise, false.

Remarks

Call the IsInputKey method to determine whether the key specified by the keyData parameter is an input key that the control uses. This method is called during window message preprocessing to determine whether the specified input key should be preprocessed or sent directly to the control. If IsInputKey returns true, the specified key is sent directly to the control. If IsInputKey returns false, the specified key is preprocessed and only sent to the control if it is not consumed by the preprocessing phase. Keys that are preprocessed include the Tab, Return, Esc, and the Up Arrow, Down Arrow, Left Arrow, and Right Arrow keys.
